The Altered States Database (ASDB) is an open data initiative that collects psychometric questionnaire data on subjective experiences from pharmacologically and non-pharmacologically induced altered states of consciousness. The current update adds data published in 2023, identified through a systematic literature review following PRISMA guidelines. Of 454 items screened, 13 journal articles were included: ten report on the 11-ASC, eight on the 5D-ASC, six on the MEQ-30, and one on the PCI. The ASDB now contains data on 22 substances and 13 techniques, from 198 journal articles and 847 datasets, accessible online.
